1) Already done.
2) Already done.
3) Done in many places
4) Not done - That should be pretty easy change.
5) Not done
6) We believe we have our server pretty nicely tweaked but we can look into that more.
7) Done - Might need a recheck since we've made some visual changes more recently.
8) We are fairly anal about speed but will look again to see if anything else could be fixed.
